During a recent interview, Akdong Musician's Suhyun talked about her brother acting jealous that she was promoting as part of the unit project HI SUHYUN.

Akdong Musicians is a brother & sister duo consisting of Chanhyuk and Suhyun. HI SUHYUN marks the first time they have not made music together.

Quote by Suhyun

[Chanhyuk] said, "My way and your way are different," and looked like he really didn't care. Instead of being jealous, he seemed more disappointed from an artist's point of view. In terms of music, there are lots of things that Akdong Musician has to show, but he was worried that my image would be wasted through HI SUHYUN.

When I kept promoting through other means, he kept saying that he would write songs and give it to other people. He even told Lee Hi, "You better not sing my songs."

Suhyun said that his brother was only joking around and pretending to be jealous of her activities without him. In reality, the two have a strong sibling bond and are grateful to be bringing their music to the world.
